Budget ~50% verification+adaptation overhead for months-old outreach lists

Aggregate from a ~25-person automated LinkedIn outreach run against a contact list only weeks-to-months old: about half the targets had changed employer, and a meaningful minority were unreachable (already connected, invite pending, or email-gated). Practical planning number: expect to verify every profile live and rewrite the personalized hook for roughly one in two, and to skip/route-around perhaps one in six. Do not assume a recent list is send-ready; the per-profile verify+adapt step is the bulk of the real work, not the sending.
